STOVEPIPE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 503,760, dated August 22, 1893.

v Application filed April 25, 1893. Serial No. 471,825. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE G. CALDER- WOOD, a citizen of the United States, residing atBiddeford, in the county of York and State of Maine, have invented a new and useful Stovepipe Attachment, of which the following is a specification.

My invention relates to stove-pipe attachments, and more especially to improvements upon the construction of attachment illustrated, described, and claimed in United States Patent No. 483,207, granted me September 27, 1892. Y

In the above patent was illustrated a metal frame adapted to be applied to an oblong opening in the upper end of the top section of the vertical stove-pipe employed at the back of a stove, and 1n said frame was located a sliding plate carrying a collar designed to be adj usted to a point opposite the stove-pipe opening in the chimney and therefore to be connected with the same bya horizontal section of pipe, thus obviating the necessity of fitting the pipe to different heights of openings in the chimneys each time the stove was set up, and also the employment of an elbow for this purpose.

The objects of my present invention are, as before stated, to improve upon this construction and to provide a cast-metal frame so constructed as to adapt it to fit neatly in the opening of the stove-pipe to form a tight j ointtherewith to be adjustable vertically so as to adapt it for connection with the pipe receiving holes of various chimneys; and to secure the above in a cheap, simple, and economic manner, and to arrange for accomplishing such adjustment with facility.

With these and other objects in view the invention consists in certain features of construction hereinafter specied and particularly pointed out in the claims.

Referringtto the drawingsz-Figure 1 is a perspective View of the upper section of a vertical stove-pipe, the same being provided with an attachment constructed in accordance with my invention. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a transverse sectional view. Fig. It is a detail in perspective of the attachment.

Like numerals of reference indicate like parts in all the figures of the drawings.

' the exterior.

The attachment consists in an oblong castmetal frame comprising the opposite vertical sides l and the upper and lower transverse connecting portions 2, the whole constituting an oblong frame adapted to fit snugly in a correspondingly shaped opening 3 with which the stove-pipe section 4 is provided.

The longitudinal sides l of the frame have `extending from their inner edges L-shaped Vof the pipe and is transversely curved to correspond with the curvature of the pipe so that the opening in which the frame is located and which is formed in the pipe is not visible from The upper and lower transverse portions are provided upon their inner edges with angular recesses 7, and adapted to take into either one of the same is a closing-plate'S. The closing-plate 8 is designed to cover a portion of the oblong opening of the frame, and may be located either at the upper or lower end thereof. Thin metal ears 9 are located at the opposite sides of the plate and overlap the frame and are provided with small oblong slots lO which register with rev versely arranged slots ll formed in the sideof the frame, as shown in Fig. 2, it being nec-V essary to reverse the plate when transferring it from one end to the other.

14 designates a metal plate transversely curved to conform with the curvature of the chimney and of the frame, and the said plate is of a length about agreeing with or slightly longer than the frame, and is of such width as to adapt it to be mounted and slid within the ways, whereby it is adjustable up and down within the frame immediately in-rear` of the filling or closing-plate. This slidingplate is provided at its center with an outwardly extending pipe-tting collar 15.

IOO

the chimney-breast with which it is desired to make connection, then by moving the sliding plate vertically the collar thereof is adjusted until it reaches a line directly transversely opposite with the opening in the chimney-breast, when a horizontal section of pipe or line of pipe will be employed to eiect ,the connection. It Will be seen that the adjustment of the collar of the plate is only limited by the length of opening in the frame. The object of using the filling or covering-plate is to enable me to secure an adjustment only limited by the length of opening in the frame and at the same time obviate the necessity of employing a commensurately longer sliding plate, but to the contrary, by the employmenty of the filling or covering plate, a slidingA plate myown I have hereto aixed my signaturein the presence of two Witnesses.v The attachment, it will be seen, is ornamental, and may be cheaply and economicallyconstructed, and furthermore, be found very useful in avoiding the necessity and exi pense of Velbows and the necessity of con- 2 no longer than the frame itself Will permit of the adjustment necessary.

stantly readj usting and increasingor decreasing the. length of the stove-pipe to t holes of different chimneys every time the stove is reset. Y

- Having described my invention, what I lclaim -is- In a` stove-pipe attachmentfor the purpose described, the combination with the oblong transversely curved metal frame having its rear ysides 'provided Withparallel vertical Ways extending inwardly from the frame, and

yits upper and lower transverse portions provided atv their inner edges with angular recesses, of. a iilling'or covering plate tting between the opposite sides of the frame at either end thereof, ears slidably located upon the zplate, the slots of the ears being disposed at right an glesto those formed in the frame, T-

jshaped keys for locking the frameand plate togi-ther, and a collar-carrying sliding-plate Zmounted in the Ways, substantially as speci- `lied.

In testimony that I claim the foregoing as GEORGE' G. CALDERW'OOD.
